I represent a company and we are currently working on a free, open source project, and we are in need of a service for determining the users ip. The project is a graphics engine to easilly create games for Windows phone 7 (found here: http://spge.codeplex.com/) and we use the client's ip for retrieving advertisments.

We currently use this library internally for commercial use, but for our own use we have already set up a server which provides an ip lookup service. I want to ask whether it is acceptable by you to provide your automated service as a default choice for retrieving a user's ip, so that users of out project can quickly start using the library, and if so do you want any information to be displayed on the codeplex site and the source files that retrieve the ip from your service.
